Intent Overview
The core components of an Android application (its activities, services, and broadcast receivers) are activated
by intents. An intent is a bundle of information (an Intent object) describing a desired action - including the data
to be acted upon, the category of component that should perform the action, and other pertinent instructions.
Android locates an appropriate component to respond to the intent, launches a new instance of the component
if one is needed, and passes it the Intent object.
Components advertise their capabilities, the kinds of intents they can respond to, through intent filters. Since
the system must learn which intents a component can handle before it launches the component, intent filters
are specified in the manifest as <intent-filter>elements. A component may have any number of filters, each one
describing a different capability. For example, if the manifest contains the following:
<intent-filter . . . >
<action android:name=”android.intent.action.DEFAULT” />
<category android:name=”android.intent.category.MAIN” />
</intent-filter>
In the Intent output plug-in configuration, the
Intentaction would be:
android.intent.category.DEFAULT
and the Intent category would be:
android.intent.category.MAIN.
The Intent delivery option allows the method by which the intent is delivered to be specified. The delivery
mechanisms are Send via startActivity, Send via startService or Broadcast intent.
The decode related data added to the Intent’s bundle can be retrieved using the
Intent.getStringExtra()
and
Intent.getSerializableExtra() calls, using the following String tags:
• String LABEL_TYPE_TAG = “com.symbol.emdk.datawedge.label_type”;
• String contains the label type of the barcode.
